Subtract 4.66 * 10 ^-5 - 7.34 * 10^-7
To subtract these numbers, we need to have the same exponent. Let's rewrite both numbers with the same exponent:
4.66 * 10^(-5) = 0.0000466
7.34 * 10^(-7) = 0.000000734
Now, we can subtract these numbers:
0.0000466 - 0.000000734 = 0.000045866
To subtract these two numbers in scientific notation, we need to ensure that the exponents are the same.
4.66 * 10^(-5) = 0.0000466
7.34 * 10^(-7) = 0.000000734
Now, subtract the two numbers:
0.0000466 - 0.000000734 = 0.000045866
In scientific notation:
0.000045866 = 4.5866 * 10^(-5)
To subtract two numbers written in scientific notation, you need to ensure that they have the same exponent. In this case, the exponents are already the same, both being -5.
To perform the subtraction, you can simply subtract the coefficients (the numbers in front) while keeping the exponent the same.
So, subtracting 4.66 * 10^-5 from 7.34 * 10^-7 would be:
(7.34 - 4.66) * 10^-5
= 2.68 * 10^-5
Thus, the result is 2.68 * 10^-5.
